New poster so please take it easy!
I'm renewing my driveway with Marshalls Drivesett Duo range blocks (my father-in-law had his drive renewed on an insurance job because of fading so I have taken the old up and am planing on putting them down), I need some advice on a few things.
The existing drive is tarmac and edged with concrete slabs, i've done an exploritory dig and have got to 300mm of hard core etc and stopped as I thought this would be deep enough to reuse. As I took the tarmac off (50mm) and then what I can only discribe as ballast (large grit sand 75mm), before hitting a very compacted hardcore layer. My 1st question is that if I take off the tarmac 50mm and the 75mm of ballast! what is the thickest depth you guys advise I can have my sharp sand, as I would be looking at 75mm?
I'm widening the drive slightly as I have some spare ground on one side and paving on the other. Once I dig this out can the tarmac be used as a hardcore substitute or is it too soft? If its too soft for the driveway, could it be used for the pathway to the side?
As you can gather from the questions, I want to save money where possible!
Last piece of advice, the shape of the drive has a curve and straight section and was looking for how the pro's would lay the blocks? I have included a map below showing the area. The grey area is the drive and the brown is where I will be widening the driveway.
Thanks for any advice.
